  • NJEFG

Fiberglass Board is made of chopped fiberglass by wet lay-out process. With our unparalleled formula and process the fiberglass board can reach the thickness 8mm till 10mm, the one layer polyporous structure make the fiberglass board has unique combination of abuse resistance and sound absorption. At the same time, the fiberglass Board has the features of heat reservation, thermal insulation and fire-proofing. Adding the excellent features of stiffness, light weight, bendable and easy cutting, the fiberglass board is very easy and simple to be further processed and installed. All these features make the fiberglass board an ideal material to improve the acoustic environment, decrease the loss of heat and keep the building safe from fire.
